Serial No. 465,705- (No model.)

To aZl whom it may concern:

Be it known that 1, JOHN F. DORNFELD, of Watertown, in the county of Jefferson and State of Wisconsin,have invented a new and useful Improvement in Malt Stirring and Aerating Apparatus, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. y,

My invention relates to that class of devices adapted to stir and thereby to break up and open the mass of grain on a malting floor, permitting air either by natural action or by artificial means, to come into contact with all 1; parts of the flooring of grain in the process of malting.

The object of the invention is to provide a strong and durable apparatus, simple in construction, and largely automatic in operation; more convenient in use, more satisfactoryin its results, and requiring less attention to operate it than has heretofore been known.

The invention consists of the apparatus and its several parts or their equivalents, hereinafter described and claimed. In the drawings, Figure 1, is a vertical section of the apparatus, in which most of the operative mechanism is seen in elevation, the mechanism being chiefly that at the left of 50 line 1-1 of Fig. 3. Fig. 2, is ahorizontal section of a portion of the apparatus, taken on line 2-2 of Fig. 1 looking downwardly; Fig. 3, is an end elevation of a portion of the apparatus. Fig. 4, is a section of a portion of the malting floor, with a conveyer for moving the malt from the malting room. Fig. 5, is a detail of a modified form of shovel.

A is the floor of the malting room. B is a fragment of the wall of averticalat- 4o temperator flue, at one end of the malting room. This attemperator flue is located at one end of the room medially.

O is the malting floor supported on posts E E, the end of which malting floor is preferably turned upwardly as seen at D in a curve corresponding substantially with the sweep of the shovels as hereinafter described. This malting floor 0 located at a distance above the floor A, is supported on posts E providing an air chamber beneath it and is perforated to permit of the passage of airtherethrough. Vertical walls F at the sidesof the floor 0 extending upwardly from the floor close the floor in at its sides, and prevent the grain or malt from escaping from the floor. A carriage 10 provided with grooved wheels 11, 11 fixed on revoluble axles 12, 12' is adapted to travel reciprocally on a track formed by rails 13 supported on the walls F and the reinforcing and supporting posts 14. The rails 13 are preferably constructed of angle iron, the upper edge or tread of which is receivedin the grooves of the wheels 11 whereby the wheels are retained on the track. Two

shafts 15, 16 one above the otherare journaled in boxes having permanent positions in the frame so that the axes of the shafts are constant relative to the carriage and to each other and are each provided with. double cranks 15' 16. These shafts near their other extremities have other cranks corresponding to those shown in Fig. 3. It will be observed that only a portion of one side of the malting floor is shown and a correspondin g portion of the carriage and the mechanism mounted thereon, as the other side of the carriage and the malting floor are substantially duplicates of the portion shown in Fig. 3. The cranks 15 and 16' are of the same length, the wrists on the cranks being at equal distances from the axes of their shafts respectively andare arranged in similar positions on the shafts and are so geared that in operation the shafts and the cranks rotate isochronously. Vertical arms 17 are pivoted and thus mounted on the wrists of the cranks 15' 16 which arms depend therefrom, and carry fixed in their lower extremities a shovel head 18 in which are fixed a series of vertically arranged shovels 19. In the form of device shown in Figs. 1 and 3 the shovel head 18 is substantially as long as the width of the malting floor G and the series of shovels 19 extends the entire length of the shovel head. These several shovels or shovel blades 19 are preferably a little distance apart, whereby they are better adapted to enter and separate the mass of grain. The relation of the carriage to the malting floor is such that the shovels at the lower limit of their movement come substantially to the malting floor and by f machine and t whiehqmesh w; a shafta'23 jflurna tacbqoi th putting it, an

1 tipn fromitheshafnlii direction in accordance W1 the motion" {the shaft 15, whereby the carriage'is 11min the direction desired. The teat-I1; H

are: so formed that; the

movable section of the floor there is a trans els T T thereon, instead of one set as shown in Figs. 1 and 3. This form of device is desirable when the malting floor is quite wide, and the advantage of having shovels so arranged is to a considerable extent, to balance the movement and strain on the machine, as

in this form of device there is more constantly and steadily a resistance to the movement, because one or the other set of shovels is nearly constantly in the grain.

What I claim as my invention, and desire to secure by Letters Patent, isy 1. The combination in a malt stirring apparatus, of a carriage reciprocable over a malting floor, a plurality of shafts journaled in the carriage distant from but parallel with each other, each shaft revolving about a distinct and constant axis, cranks on the several shafts, wrists on the cranks at equal distances from the axes of their shafts respectively, and

vertically disposed shovels mounted onthe wrists of the cranks, whereby by the synchronous revolution of the shafts the shovels are revolved in a constantly vertical position, substantially as described.

2. In a malt stirring apparatus, a malting floor, a track adjacent to the floor, a carriage arranged to travel on the track, vertically disposed shovels mounted transversely of the floor in an arm or arms pivoted on the wrists of a plurality of cranks revolving isochronously and describing equal arcs about diiferent parallel and distant axes in the carriage, all combined substantially as described.

nation with a traveling carriage, of a plurality of horizontal parallel shafts, cranks on the shafts, wrists on the cranks at equal distances from the axes of their shafts, an arm or arms mounted on the wrists, and vertically disposed shovels fixed in the arm or arms so as to move in vertical circles in vertical positions constantly, substantially as described.

4. In a malt stirring apparatus a traveling carriage, a plurality of horizontal cranked shafts journaled in the carriage unitedly carrying vertically disposed shovels moving in a circle vertically and adapted to dip intermittingly into and stir the grain, cog wheels on the shafts, an interposed pinion meshing with the cog Wheels, means for communicating motion to the pinion, and means connected operatively to one of said shafts and to an axle of the carriage, for reciprocating the carriage adjacent to'the grain, substantially as described. V

5. In combination with a perforated malting floor and a malt-stirring apparatus, a device for cooling and attemperating the air admitted thereto, consisting of achamber in the also water therein, whereby the chamber can be hermetically sealed, substantially as described. I

In testimony whereof I affix my signaturein presence of two witnesses. i
